While not entirely true, this story is based on a true series of events involving my wife and a coworker.
It started as a game and soon became something much more. More dangerous. More exciting. More.
My wife, Mary, has always been extremely sexual in nature. She initiated our first encounter by banging on my bedroom door in the middle of the night and totally devouring my cock. She seemed wild and out of control. I learned later what initiated that.
As our relationship blossomed, I became both amused and aroused by the dichotomy of her personality. She was a sweet, outgoing, wholesome Southern girl, who could turn into a cock-starved slut with little notice. I was the lucky recipient of that passion and I was not complaining.
She had a wide, inviting smile for everyone she met, which I soon discovered was interpreted by many men as a smile foretelling a blow job, or other nefarious acts. I don't know if my Mary intended it that way, but her effect on others was obvious.
We did marry and we entered a stage of marital bliss that was beyond my imagining. Beyond just her sweet, loving personality, she also discovered the joys of sex in dangerous and semi-public places. I can't tell you the number of places we fucked where the risk of getting caught was extreme, matched only by the pleasure.
I knew she could have any man she wanted, but she chose me, and I was determined to make sure that I was worthy of her love.
Once, she was telling me about a guy at work and how they kept having conversations about sex. She was surprised that he and his wife were not playing and exploring like we were, and she felt sorry for him. She tried to encourage him by telling him about some of our adventures, in the hopes that this would help him pursue the same kind of fun we had. She confessed to me that these conversations got her very horny, and if she couldn't wait for me at home, she'd have to excuse herself to the bathroom and make herself cum, all the while trying to restrain her moans and screams while she came.
She told me that once, as she took the elevator to a different floor to find a restroom for relief, her co-worker, Bill, jumped on the elevator with her. She said he seemed uncomfortable, while they chatted, and then, as he was about to exit the elevator before her, he turned and kissed her. He started carefully, but when she didn't pull back, he began to explore her mouth with his tongue, and his arms wrapped around her and pulled her close. She told me everything: how she responded forcefully because she felt she was close to coming even before the elevator doors closed; how she could feel his cock pressing against her, and how, after he retreated from the elevator, she went to the bathroom and made herself come three times in quick succession. She told me it was like throwing gas on a fire. She told me this as she was riding my hard cock to three more orgasms and I was not in a position to take offense.
After our passion subsided, she apologized to me for leading him on. She knew it was wrong and she'd have to straighten it up with him tomorrow. I told her not to worry about it. In fact, I suggested what I thought would be a fun and interesting game. I knew he would be encouraged by his success that day in the elevator, but I suspected that he would be hard pressed to go farther.
"Mary", I said to her earnestly, with my cock rising to attention in very quick order "I want you to do something for me. This is very important and I don't want you to refuse."
I'm sure she assumed I was going to tell her to quit her job and leave Bill as a distant memory. "Okay, Jack, what is it. I'll do anything for you."
"If Bill comes on to you again, I don't want you to refuse him. If he wants to kiss you, kiss him back with your tongue. If he wants to feel your tits, I want you to bare them."
She looked strangely at me, as if I was trying to trick her. But I could tell she was aroused as her nipples grew hard and her breathing quickened.
"I mean it. If he presses his cock against you, I want you to take it out. Do you understand?"
She averted my gaze, and answered meekly, but compliantly, "yes, I understand." I sensed a hint of a smile as she answered. After a few moments, she asked me, "What if he wants me to suck him off? I told him I do that for you and he was very jealous."
"then I want you to suck him, and let him come on you." And with that, she ducked her head down and began to suck on my cock.
"What if he wants to fuck me?" she asked, temporarily dropping my rock hard and encouraging cock from her mouth.
"then, without thinking, you'll bend over a desk, or straddle him on a chair. But you'll fuck him. What he asks, you'll obey, but you wont tell him I know."
She groaned enthusiastically and she proceeded to climb on top of my cock and we made love again until we were both too tired to move. We fell asleep tangled together.
The next day, I arose and got ready for work before Mary even woke up. I barely thought of our conversation as I began to prepare for the day ahead. I kissed Mary good bye and headed to work without a moment of thought or hesitation. That day and the next, and the three after that, were normal as far as I could tell. The routine of the days took over and all seemed as it had been.
